Summaa

This report provides the results of an Instrument Drift Analysis performed for Indian Point 3 (1P3)

Nuclear Power Plant's Reactor Protection System (RPS). The Instrument Drift Analysis is divided

into two parts. Part one assesses the actual past instrument drift, in order to comply with item one

of Enclosure 2 of the NRC's Generic Letter (91-04). Part two assesses the predicted future

instrument drift, in order to comply with items two, three and four. The scope of this report covers

all the components in the RPS system that are calibrated once every 18 months. The methods used

to predict instrument drift for 30 months are documented. The purpose of this Instrument Drift

Analysis is to assess the acceptability of extending the calibration interval for instrumentation

addressed in the RPS system from 18 t o a maximum of 30 months. This analysis can be used as a

basis to determine whether the calibration intervals for RPS can be extended to support the 24 month

operating cycle.

Introduction

According to the NRC, licensees should address the issue of instrumentation errors caused by drift.

This should be done in order to justify an increase in surveillance intervals to accommodate a 24

month operating cycle. This report addresses the following issues discussed in Enclosure 2 of the

NRC's Generic Letter (91-04):

1. Confirm that instrument drift as determined by As-Found and As-Left calibration data from

surveillance and maintenance records has not, except on rare occasions, exceeded

acceptable limits for a calibration interval.

2. Confirm that the values of drift for each type (make, model, range) and application have

been determined with a high probability and a high degree of confidence.

3. Confirm that the magnitude of the instrument drift has been determined with a high

probability and a high degree of confidence for a bounding calibration interval of 30

months for each instrument type (make, model number and range) and application that

performs a safety function. Provide a list of the channels by TS section that identifies

these instrument applications.

4. Confirm that a comparison of the projected instrument drift errors has been made with the

values of drift used in the setpoint analysis. If this results in revised setpoints to

accommodate larger drift errors, provide proposed TS changes to update trip setpoints. If

the drift errors result in a revised safety analysis to support existing setpoints, than a

summary of the updated analysis conclusions to confirm that safety limits and a safety

analysis assumptions are not exceeded must be provided.

The purpose of this report is to provide an Instrument Drift Analysis, along with the methodology

and assumptions used to determine instrument drift for Indian Point 3 (P3) Nuclear Power Plant's

Reactor Protection System (RPS). The above four issues will be the basis used to determine if the

results of this Instrument Drift Analysis will support an increase to a 24 month operating cycle.

Instrument drift for the RPS system was determined for components that require calibrations every

18 months, based upon historical plant calibration data. The following is a list of affected calibration

procedures in the RPS system:

3PC-R1A: Reactor Coolant Loop Narrow Range Temperature instrumentation Calibration

3PC-R1B: Reactor Coolant Loop RTD Calibration - AT

3PC-R2: Reactor Coolant Loop Flow Calibration

3PC-R3: Pressurizer Level Calibration 3PC-R3A: Pressurizer Level Transmitters' Check and Calibration

A complete list of components evaluated in the Instrument Drift Analysis for the RPS system is

included in Table 1 of this report. Calibration data was also extracted as necessary from work

requests. Any calibration procedure that had a work request associated with it was documented on

the data sheets under the section labeled 'Notes".

An example of a typical calibration for a level transmitter is as follows:

1. Close both of the high and low side isolation valves.

2. Open the equalizing valve.

3. Slowly open the high and low side vent.

4. Slowly open the high and low side test connection.

5. Remove drain plugs from both high and low sides. Remove all water.

6. Install the low side drain plug and close its vent.

7. Close the equalizing valve.

8. Connect a pressure gauge at the input of the transmitter.

9. Connect a digital voltmeter (DVM) across a test resistor at the output of the transmitter.

10. Exercise the transmitter using the calibration setpoint to obtain a maximum and minimum pressure reading.

11. Adjust the input pressure to the transmitter at 5 discrete points across the full span in both directions.

-2-


12. Record the As-Found output reading from the DVM for each design input pressure reading.

13. If any of the As-Found output reading readings are not within their calibration tolerance, adjust the zero and/or span adjustment screw until the desired output DVM reading is reached.

14. Record the As-Left output readings.

15. If the transmitter needs no adjustment, then the As-Left values shall be the same as

the As-Found values.

Part one of this Instrument Drift Analysis assesses actual past instrument drift. Actual past instrument

drift for a given period was compared to a Vendor Drift Allowance (VDA) for a period of similar

length or the Calibration Tolerance (CT). This analysis determined whether each individual

instrument drift value was within acceptable limits for that calibration interval. Appendix A and B

of this report provide the results of this analysis, and Table 2 and 3 provide a summary.

The second part of this Instrument Drift Analysis assesses the predicted future instrument drift. A

Maximum Expected Drift for 30 months (MED30) was determined from the average and standard

deviation of actual field calibration data statistically extrapolated to a 30 month period. Data from

components within the same calibration procedure, having the same model number, manufacturer, calibration span and application were combined, when appropriate. MED30 is expressed as a percent

of the calibration span (%CAL-SPAN). Only drift values with calibration intervals between 100 and

675 days were included in the database, unless otherwise stated.

Once the Maximum Expected Drift for 30 months (MED3O) was calculated, it was compared to the

Vendor Drift Allowance extrapolated to 30 months (VDA3O) or the calibration tolerance (CT).

MIED30 is a statistical limit derived from past calibration data. Appendix C and D of this report

provide the results of this analysis and Table 4 and 5 provide a summary.

Past Drift

An assessment of actual past instrument drift was performed (Appendix A and B) to determine

whether individual drift values for a given calibration interval are within acceptable limits.

Instruments having 80% or more of their past drift values within VDA. (Appendix E) or the

CT are considered to have an acceptable performance record. The results of this assessment

are summarized on Tables 2 and 3.

1. Pressurizer Pressure Transmitters (PT-455, 456, 457, 474) exceeded acceptable limits 9 out of 12 times. This was attributed to faulty zero suppression kits, which were

replaced on December 4, 1990. After installing the new zero suppression kits, As-Left calibration data was within the Calibration Tolerance (CT).

2. Steam Generator Level Transmitters (LT-417A, B, C; LT-427A, B, C; LT-437A, B, C; LT-447A, B, C) exceeded acceptable limits 19 out of 36 times for the Maximum Drift point data sheet. Since these values exceeded acceptable limits, an Actuation

- 25 -


Point data sheet was constructed. This data sheet showed that 12 out of 36 data points

exceeded acceptable limits. However, the increase in acceptable data points was still

insufficient to conclude that these transmitters were within acceptable limits on more than rare occasions.

3. Pressurizer Level Transmitters (LT-459, 460, 461, 462) exceeded acceptable limits

5 out of 6 times for the Maximum Drift Point datasheet. Since these values exceeded

acceptable limits, an Actuation Point data sheet was constructed. Again, these

transmitters exceeded acceptable limits; 4 out of 6 times for High Level Reactor Trip at 460 mV.

4. Undervoltage Relays (27-1A, 2A, 3A, 4A) exceeded the CT 7 out of 9 times.

The assessment of predicted future instrument drift was performed (Appendix C and D) to

determine whether predicted future drift values are within (VDA30) (Appendix F) or the

(CT). The results of this assessment are summarized on Tables 4 and 5:

Since future drift values for the above components are expected to be within calculated

vendor allowances, their calibration interval can be extended to a maximum of 30

months.

Since most of the past As-Found values were out of tolerance for the Steam Generator Level

transmitters, MED30 for the Maximum Drift Point and Actuation Point data sheets exceeded

VDA30. In discussions with plant personnel, poor instrument performance was attributed to

Steam Generator cleaning methods. The cleaning process permitted particulate matter from

the steam generator tubes to enter the reference legs and cause contamination of the level

transmitters. The Steam Generators have been replaced and the reference legs are now isolated

prior to any Steam Generator cleaning work. Due to these changes, future drift values are

expected to be within VDA30. A review of 1992 calibration data (see appendix B&D, pages

12-14) confirms that future drift values were within VDA. Therefore, the calibration interval

- 27 -


for these transmitters can be extended to a maximum of 30 months. Future As-Found conditions should be within 1.5256% of the calibration span (VDA30).

2. As expected, MED30 for the Pressurizer Pressure transmitters was well above VDA30 due to poor past performance of these transmitters. Since new zero suppression kits were installed future drift values are expected to be within the VDA30 of 1.0775 percent of the calibration span. However, a review of 1992 calibration results shows improper test equipment was used and confirmation that transmitter performance will be within vendor allowances could not be validated. Therefore, the calibration interval for PT-455, 456, 457, 474 cannot be extended.

3. MED30 for the Pressurizer Level transmitters was above VDA30 by over 14% of the calibration span for the Maximum Drift Point and Actuation Point data sheets. One reason for this large difference was due to the lack of data points used to calculate MED30, which increased the K factor. However, since past performance of these transmitters routinely exceeded allowable limits and a large calibration uncertainty is predicted for future performance, the calibration interval should not be extended.

4. MED30 for the Pressurizer Pressure Lead/Lag Units (Lead Time) was above VDA30 by over 2 % of the calibration span. The reason for this difference was due to one data point, which was so large that it could be considered to be caused by calibration error. Therefore, the calibration interval for these components can be extended to a maximum of 30 months. Future As-Found conditions should be within 3.1 sec. (MED30) 95 % of the time.

5. MED30 for the Reactor Coolant Loop RTD-AT Special Lag Units was above VDA30 by over 9 % of the calibration span. One reason for this large difference was due to the lack of data points used to calculate MED30, which increased the K factor. Also, one data point was so large that it could be considered to be caused by calibration error. By removing this drift value from the database, and using a smaller K factor, MED30 would be within VDA30. With one exception, past performance of these components was consistently within allowable limits (VDA), future As-Found conditions should be within 1.42% of the calibration span (VDA30). Therefore, the calibration interval for these Special Lag Units can be extended to a maximum of 30 months.

6. MED30 for the 6.9KV Undervoltage Relays exceeded the CT by over 40% of the calibration setting. Two reasons for this large difference are: 1) the increased K factor associated with limited data, and 2) the 27-3A relay exhibited significantly greater drift than the other relays.

Since past performance of these relays routinely exceeded the CT and the predicted calibration uncertainty is too large (Reference 13), the calibration interval should not be extended.

7. MED30 for the 6.9KV Underfrequency Relays exceeded the CT for both Relay Trip and Time Delay. Two reasons for this large difference are: 1) the increased K factor associated with limited data, and 2) the extrapolation of field data which results in unrealistic drift values.

- 28 -


However, since past performance of these relays are consistently within the CT for both Relay

Trip and Time Delay, the calibration interval can be extended to a maximum 30 months.

Future As-Found conditions should be within 0. 4508 % (MED3O) of the calibration setting for

the Relay Trip portion and 19.3159% (MED3O) of the calibration setting for the Time Delay portion.

Conclusion

The preceding sections of this report provide the results of an Instrument Drift Analysis. A list of

components for the RPS system covered in this analysis is in Table 1 of this report.

Past Drift

An assessment of actual past instrument drift was performed in order to determine whether individual instrument drift values were within vendor allowances calculated for that calibration interval. Appendix A and B provide the results and Table 2 and 3 provide a summary of this analysis.

Overall, past instrument drift for the majority of the RPS components did not, except on rare occasions, exceed acceptable limits for a calibration interval. Devices which were exceeding acceptable limits were previously replaced, repaired or otherwise modified to preclude recurrence.

Future Drif

MED30 was calculated and compared to VDA30 or the CT. MED30 was compared to the CT only when information regarding vendor specifications was not available. A summary of this comparison is provided in Table 2 and 3 of this report. For cases where MED30 was less than or equal to VDA30 or the CT, future instrument drift will be within acceptable limits for a maximum calibration interval of 30 months. However, for cases where MED30 was greater than VDA30 or the CT, credit was taken, for instrument repairs and extrapolation of field data which results in unrealistic drift values, to justify the longer calibration interval.

Overall,the differences in As-Found and As-Left calibration readings were assumed to be entirely due to drift, instrument accuracy, and measuring and test equipment uncertainties; even though other factors such as calibration uncertainties and technician errors were present. This analysis provides a conservative assessment of RPS instrument performance.

Future drift is predictable and can be used as a basis to extend the calibration interval for components in the RPS system from 18 to a maximum of 30 months.

There are three notable exceptions:

1) Pressurizer Pressure Transmitters (PT-455, PT-456, PT-457 and PT-474).

2) Pressurizer Level Transmitters (LT-459, LT-460, LT-461 and LT-462).

3) 6.9KV Undervoltage Relays (27-1A, 27-2A, 27-3A and 27-4A).

The above components have experienced unpredictable high drift and a lack of acceptable past performance. Therefore, the calibration interval for these components should not be extended until a pattern of acceptable drift values can be established.
